Project Sputnik

Project Sputnik is the real-time in-building location tracking system present at the 23C3. The Sputnik is a small active 2.4GHz RF Beacon, whose signal is picked up by one or multiple of the 20+ Sputnik base stations installed in the event venue (bcc). Attendees of the 23C3 are able to voluntarily participate in this system by purchasing an inexpensive Sputnik transponder which they can carry with them during the whole event. In order to make this project attractive to hackers, the Sputnik hardware schematics and firmware source code will be published on the first day of the event, enabling hackers to enhance/replace the exiting firmware, and to add new applications such as peer-to-peer communication between multiple Sputniki. The location data (both raw and processed) will be available to the public via the congress network. This means that everyone has access to all data. The intention of the project is mainly to demonstrate what kind of surveillance is possible using off-the-shelf inexpensive technology, and to make hackers interested into exploring potential positive use cases for it.
